Make the UPGRADING note about ArrayObject more explicit.

We noticed the BC break when testing `curl_setopt()`, and hadn't interpreted
this note as affecting internal functions in general, so this adds a sub-bullet
to note that.

This overlaps a bit with the previous bullet, but since I don't know exactly
which operations were in mind at the time, I've elected to preserve them both.
Bits are cheap.

Make the $num_points parameter of php_imagepolygon optional

That parameter is mostly useless in practise, and likely has been
directly ported from the underlying `gdImagePolygon()` and friends,
which require that parameter since the number of elements of the point
array would otherwise be unknown. Typical usages of `imagepolygon()`,
`imageopenpolygon()` and `imagefilledpolygon()` pass `count($points)/2`
or hard-code this value as literal. Since explicitly specifying this
parameter is annoying and error-prone, we offer the possibility to omit
it, in which case the `$points` array must have an even number of
elements, and the number of points is calculated as `count($points)/2`.

Implement union types

According to RFC: https://wiki.php.net/rfc/union_types_v2

The type representation now makes use of both the pointer payload
and the type mask at the same time. Additionall, zend_type_list is
introduced as a new kind of pointer payload, which is used to store
multiple class types. Each of the class types is a tagged pointer,
which may be either a class name or class entry. The latter is only
used for typed properties, while arguments/returns will instead use
cache slots. A type list can contain a mix of both names and CEs at
the same time, as not all classes may be resolvable.

One thing this is missing is support for union types in arginfo
and stubs, which I want to handle separately.

I've also dropped the special object code from the JIT implementation
for now -- I plan to add this back in a different form at a later time.
For now I did not want to include non-trivial JIT changes together
with large functional changes.

Another possible piece of follow-up work is to implement "iterable"
as an internal alias for "array|Traversable". I believe this will
eliminate quite a few special-cases that had to be implemented.

Closes GH-4838.

ReflectionType::__toString() will now return a complete

that relied on nullability being absent should have been pushed
to ReflectionNamedType::getName() by the deprecation of
ReflectionType::__toString() in PHP 7.1 / PHP 7.4.

Add fdiv() function

The fdiv() function is part of the fmod() / intdiv() family. It
implements a floating-point division with IEEE-754 semantics.
That is, division by zero is considered well-defined and does not
trigger any kind of diagnostic. Instead one of INF, -INF or NAN
will be returned, depending on the case.

This is in preparation for throwing DivisionByZeroError from the
standard division operator.
